This may well be in the archives, but the search function isn't working and I'm too impatient to wait.

I have a brand-new 25-pound bag of clay, and it's incredibly soft (in spite of sitting around for at least four months!) - unfortunately it's a bit too soft for throwing anything more than a 1/2-pound at a time without collapsing. I tried kneading the clay on an absorbent surface first, but it wasn't enough.

What's the best way to dry out the clay enough to throw? I don't want it to get too dry...I don't have a pugmill, so reclaiming is a long and arduous process. Any suggestions are appreciated!!
